TANGS.

To all whom it may concern:

Be it known that we, HERMANN WASS- MUM), ARTHUR Mi'i'LLER, and ERNST MI'J'LLER, subjects of the German Emperor, and all residing at Berlin, Germany, have invented certain new and useful Improvements in Tangs, of which the following is a specifi-- cation.

This invention relates to hollow tangs, and a primary object is to provide an improved attachment exchangeably securing the blade of a knife, fork or the like therein.

The invention substantially consists in connecting the tang of the blade by means of a removable insertion with a known hollow tang consisting of iron or of some other suitable met-a1, to be secured in the handle, the said insertion filling up the space be tween the blade-tang and the hollow tang and, if desired, permitting the blade-tang to be immovably secured in the hollow tang by soldering. Such an attachment of the blade-tang is not only cheaper, but also materially more secure than attachments known heretofore, as the said insertion securing the blade-tang is prevented by the hollow tang from deviating laterally and the handle is relieved from any. possible lateral pressure exerted by the insertion.

Three embodiments of the invention are represented by way of example in the accompanying drawing, wherein Figures 1 and 2 are vertical sections taken in planes at right angles to one another showing one form of the improved attachment, Fig. 3 is a like view showing another form, and Fig. 4 a like view showing a third form.

Referring firstly to Figs. 1 and 2, a designates a hollow tang provided with the bolster b. The blade 0 is held in position in a known manner in the slot 9 in the bolster and its tang clvprojects into the hollow tang. The blade-tang d is attached in the hollow tang in this form by means of insertions composed, for exam le, of a well-known metal composition 6 illing up the intermediate space between the blade-tang and the hollow tang. In order to give the metal composition a firm hold, the tang cZ is pro- Specification of Letters Patent.

vided with notches f. Such notches may also be provided in the interior wall of the hollow tang a if desired. Since the composition liquefies at a certain relatively low temperature, the insertion can be melted by exposing the attachment to this temperature and the blade can thus be at once exchanged.

Secondly, in the illustrative embodiment 0 according to Fig. 8' the intermediate space between the hollow tang a and the bladetang d is occupied by two insertions m, it formed to fit in the hollow tang and connected 1n suitable manner with both the hollow tang and the blade by soldering. Obviously, this arrangement also at once admits of the blade 0 being readily exchanged.

Thirdly, referring to Fig. i, the form here shown is distinguished from those described above merely by the insertion being united with the blade-tang to form a plug it which fits in the hollow tang a and is connected therewith by soldering.

We claim The combination with a blade having a tang on one end thereof and the sides of the blade and tang being continuously flat and smooth in opposite directions from the SO juncture thereof, of a handle tang being of one piece, forming a hollow body and having an opening to receive the blade tang and of sufiicient size to rovide clearance between the blade tang and the Wall of said opening, said handle tang having an outwardly projecting bolster at the blade end thereof and formed of material of great resistance and high melting point, and a metallic insertion body removable by melting at a comparatively low temperature, filling said opening surrounding said blade tang, substantially as described.

In testimony whereof, we aflix our signatures in the presence of two witnesses.
